Absorption / reflection of sunlight - Understanding …

WebAbsorption of sunlight causes the molecules of the object or surface it strikes to vibrate faster, increasing its temperature. This energy is then re-radiated by the Earth as longwave, infrared radiation, also known as … WebThe reason a dark object like an asphalt road gets hot quickly is that colors like black absorb most wavelengths of light, and therefore absorb more energy in the form of thermal energy. In the same way, the melanin in your skin absorbs the UV from the sunlight because it is so dark, and protects your skin from it. shelly e liss https://obiram.com

WebApr 13, 2008 · When they're reflected, basically the wiggle the wavelength imparts to the material creates another light wave of the wavelength of the colour that you see. That's … WebColored objects, on the other hand, reflect back only some of the wavelengths; the rest they absorb. For example, if white light shines on a red ball, the ball reflects back mostly red light, and so we see red. Most of the greens and blues that are part of white light are absorbed by the ball so we cannot see them.

WebWhite and shiny silvery surfaces are the worst absorbers, as they reflect all visible light wavelengths. Poor absorbers are also poor emitters, and do not emit radiation as quickly as darker colours. WebConcrete does a very good job of reflecting solar energy. That is the finding from a Portland Cement Association (PCA) study which measured the solar reflectance index (SRI) of 45 concrete mixes. Lighter colored materials (such as concrete) generally have a higher solar reflectance. They reflect heat from the sun and do not warm the air very much.
